| Abstract | In the controlled airspace, safe aircraft separations have to be guaranteed by the responsible controller of the sector. For safe separation the controller has to apply horizontal or vertical separation. Conventional radar displays represent the information in 2 dimensions (2D). With such displays, the horizontal separations between various aircraft are easily perceptible by the human operator. In case the horizontal separation is not guaranteed any more, vertical separation has to be applied. Vertical separation is based on data collected from the secondary surveillance radar (SSR). These SSR data contain the flight altitude information from the aircraft beside other information. The altitude information is expressed in flight levels (FL) as three digit numbers in the second line of the label associated with the aircraft symbol. Therewith the FL information is not exploitable from the controller with the first glance on his operational display system (ODS). For the vertical separation the ATCO (air traffic control operator) has to permanently scan, read, memorize and compare the shown flight level numbers of all tracks under his responsibility. Therewith the controller creates in his mind a mental picture of the traffic situation. This task requires a strong mental effort from the controller. Based on the idea that for a controller applying vertical separation to two aircraft, a priori it is more important to know that these aircraft are flying on different FL, then extracting the real FL numbers from the labels and comparing them. The proposed tool introduces a mobile horizontal filter function to answer quickly with: 'the same' or 'a different' FL. The mobile horizontal filter is moved in the steps of the used flight levels (..., 220, 230, 240, ...) with the wheel of a mouse. The mouse wheel represents a simple and quick way to move the basis of the filter which acts as reference flight level. All aircraft flying the selected reference flight level are displayed graphically to stand out of all other (flying higher or lower) displayed aircraft and can so be identified easily in a first glance. The mobile horizontal filter function moved by the mouse wheel, supports controllers permanent scanning, reading and comparing tasks for the vertical separation. It stimulates controllers to see their actual traffic situation under another aspect. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
